Maintenance Requirements
Keep your ERV performing at its best by cleaning it as described
below:
RISK OF ELECTRIC SHOCK OR INJURY.
• Before servicing or cleaning the unit, unplug the
unit line cord.
• Make sure unit is not running before opening its
door. Blower wheels are sharp and can cut.
• Do not disable the interlock switch: it is there for
your safety.
Service lters regularly:
Service lters every three months when the unit is in regular use
or as needed to keep them reasonably clean.
1. Release cam latches and carefully swing access door open.
Remove the door by sliding to one side.
2. Remove lter clips and pull out the lters.
3. Vacuum core and lters with a hose attachment.
4. Re-install lters and lter clips, (see above).
5. Re-install door, and fasten cam latches.
NOTE: The lters should be replaced after they have been cleaned
several times. The primary contact for replacement lters for
your S&P unit is the installing contractor. As an alternative, you
may wish to produce your own lters.
Filters may be cut from a sheet or roll of ¾” - 1” rm, spun
polyester lter media or material, similar to the existing lter in
the residential unit.
The size of each lter (2 required per unit) is as follows:
90-Series - 9 ½” x 10 ½”
NOTE: Filters must be used or the face of the energy exchange
core will become blocked by dust. The lters supplied in the
unit are usually able to keep the energy exchange core clear
for many months. Finer lters can be used but must be cleaned
more often.
Clean the face of the energy exchange core yearly:
1. Remove the lters (see above).
2. Vacuum the exposed faces of the energy exchange core with
a soft brush attachment.
3. After servicing the lters, re-install them (see above).
4. Vacuum out dust from the rest of the unit case.
Dust collects only on the entering faces of the energy exchange
core. The interior of the energy exchange core stays clean even
if the core faces are dust covered.
DO NOT WASH THE ENERGY EXCHANGE CORE.
Clean only as described above. The energy exchange
core can be replaced but is expensive.
